        Which is awesome, but then it shouldn’t cost this much.

        Unless if it’s made of some of the actually ultra high performance plastics, like maybe polycarbonate or carbon fiber reenforced PA-6/PPA for example, but I highly doubt that’s the case

          carbon fiber reenforced

          Great for strength, bad for impact resistance. You’d want a non-filled material or at least less stiff filler. Something like aramid (kevlar) would give you good properties across the board for an application like this though.

            Carbon fiber can’t handle impact? Nonsense! I’ve got a Stockton Rush paper right here proving otherwise! He even built a whole submersible to go down to the titanic. Next thing you say it won’t handle pressure cycling either? Poppycock!

            I have machined a lot, and I mean a lot of aramid filled materials of different kinds in a lot of situations. There is no way, under any circumstances I am letting that stuff near a drinking vessel I actively use, even if it is properly sealed. That shit is like hell on earth to be exposed to.

              Fair, though I wasn’t thinking of machining in this case. But yeah, my experience isn’t generally related to food safe stuff, so I don’t always think about it. Not too much concern about that on subs, helicopters, jets, etc.
